[gradsusr] Grabbing Max and Min Values from Array

Hello,
I am having trouble trying to figure out how to grab the max and min values
from an array that I read in. For instance, I have a text file that gets
created that includes the timestep, latitude and longitude values
(space-delimited) like so:
0 23.50 291.36
1 24.17 290.55
2 24.81 289.80
3 25.24 288.96
4 25.55 287.92
5 25.84 286.89
6 26.06 285.87
7 26.14 284.98
8 26.28 283.90
9 26.53 283.00
I read this file in with GrADS using the following code and create an array
for latitude and longitude based off the tstep:
istat = 0
while (istat != 2)
data = read('file.txt')
istat = sublin(data,1)
if (istat = 2);break;endif
line = sublin(data,2)
tstep = subwrd(line,1)
lat.tstep = subwrd(line,2)
lon.tstep = subwrd(line,3)
endwhile
rc = close('file.txt')
So, what I want to do is grab the max/min latitude and longitude values so
that I can create a domain that nicely encloses the data I have to plot. Is
this possible to do within GrADS? I didn't have any luck playing with the
max() function.
Thanks!
